My invention relates "to fly. traps mild-it "has for itsobject to provide anarran'gement that is simple in construction, neat in apj chamber 13in which the gasor vapor of the disinfectant,collects. It will be noted that pearance'andefi'e ctive in operation to entrap and destroy flies man entirely sa ita y manner. I V

provide a described whlch comprises arontamerfor formaldehyde or similar disinfectant, the

vaporof which is, fatalto flies or other insects. "A gas chamberfwhich' is located above the container, is provided with a translucent glass top to admit'light and thereby attract the flies into the chamber.

Upon being overcome by the fumes of the disinfectant, the flies fall into the liquid below. A casing of sheet metal or other opaque material renders the interior and contents of the trap invisible.

The details of my invention will be described in connection with the accompanying drawing in which Figure 1 is a side view, partially in elevation and partially in section, of a fly trap. Fig. ,2 is a top view, partially in plan and partially in section on line IIII of Fig. 1, of the device of Fig. 1.

A cylindrical base member 1 constitutesa container for a liquid disinfectant indicated at 2, such as, for example, formaldehyde, or othersuita'ble substance, the vapor of which is destructive to flies and other insects. with a neck portion 3 through whichvapor may be emitted and such insects as are overcome by the vapor may fallinto the liquid disinfectant.

A ring 4: of absorbent material, such as felt or wicking, whichsurrounds the neck portion 3, receives the bait for attracting three spring clips 6 which engage a circumferential groove 7. The casing is provided with a glass top .8 which i n transparent,

but which admits suitcase light: te -attract the flies upward-after they have enteredth'e opening 9 between the base memberandjthe casing.v 'The top'8 and the casing 5 are'de- 'tachably connected by means of lugs or projections 10' which,in"assembling these parts, pass through notches l l in the flange I2 of the casing. Thetop is then rotated until the lugs 10 are out of register with the notches 11;

The interior of the top 8 constitutesa i the diameter of the lower portion of the top bf the container immediately below it. This .arr'angementiinsures that any flies falling from thegas chamber 113 will fall v into the In the operation are thus retained under conditions which op erate to efl'ectively destroy them and, in addition, all germs that may be carried by them.

The vapors inside the trap thoroughly disinfect it at all times. The flies are in' visible after entering the trap, thus render- I oftheldevice, flies; will be attracted through the opening 9 by the bait'upon the ring 4. After rising from the ing the latter free from the objectionable features attending the use of open or transparent devices.

Itwill be noted that the entire operation of the device is performed in a strictly san itary manner which renders its use not only entirely safe, but frees it from odors or other disagreeable features. By reason of the detachable connection of the several parts, the

trap my be easily inspected and the supply of disinfectant replenished at desired inchamber shall pass into said container, and
